. n uul Told NM amwzo THE MANTLE LAMP COMPANY OF ILLINOIS.

To all whom it may concern Be it known that we, CORTLAND W. DAvIs and VICTOR S. JOHNSON, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hydrocarbon Burners; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use thesame.

This invention is a hydro-carbon burner of the blue flame wick type adapted for the production of heat or light.

In burners of this classification, it has been observed that parts of the burner adjacent theflame absorb heat from the flame and transmit the same to their supporting elements thereby causing the burner structure to become excessively heated. This unrestricted heat transmission results in what is known as creeping up of the flame.

In blue flame burners, and. especially those adapted for use in connection with incandescent mantle lamps, the creeping up defect has been found of considerable annoyance. This defect renders it very diflicult to position the wick properly. Not infrequently an operator will set the wick a little too high whereby after the fuel increases,

due to creeping up, the flame is beyond the capacity of the burner, "resulting in im'- perfect combustion and depositing of carbon deposits on the mantle.

An object of this invention is to overcome the defects above stated and to insulate parts of the burner from their supporting elements, thereby restricting heat from disseminating throughout the burner structure, and especially to segregate or insulate the parts adjacent to the flame from their supporting elements, thereby increasing the efliciency of the burner by reducing the creeping up of the flame.

It is an aim of the invention, also, to retain the heat in'the parts of the burner adj acent the flame, thereby restricting the carbon crust from forming on these parts and interfering with the air introduction to'the flame, while at the same time assisting combustion by helping keep the fuel in a hot vaporized condition.

A further purpose of the invention is to simpli y he censtructi n of a burn r, in-

able results, such as over production of fuel and creeping up of the flame. It proposed to interpose heat-resistingmaterial between the spreader and the inner W101! tube, be-

tween the flame protecting flange and the outer wick tube, between the gallery, or parts thereof and the base of the lamp between parts of the burner base, or aily combination of such insulating means as will produce the desired result. By so doing, the heat will be retained in those parts nearest the flame to assist in the combustion of fuel. while the parts of the burner which will aflect the wick, other than at the homing point, will be maintained in a comparatively cool condition.

By insulating parts of the burner from other parts thereof, we refer to any means recognized as a non-conductor of heat or to material which will resist the transmission of heat.

In the embodiment of the invention disclosed in Fig. 1, the burner is shown as comprising a basket base 1 and a plurality of members 4, 7 and 8. The lower or basket member 1 is preferably perforated as shown at 2 to leave narrow bridges of metal to assist in the dissemination of any heat which may be conducted to the base from the flame before the heat can be transmitted to that portion of the base which contacts with the fuel supply. The base may be provided with suitable means to secure it to a reservoir. The member 4 is designed to be clenched or otherwise suitably secured to the base 1. Lower member 1 is shown provided with a rib 3, around which a depending flange 6 of the member 4 may be bent to retain a suitable heat resisting material, such as a ring of asbestos, between the members 1 and 4 and to maintain these parts out of metallic contact. The gallery of Fig. 1, is shown provided with the plurality of sections above described. Upon the section 7 which may be imperforate, is mounted the cone cap section 8. On the section 7 may also be mounted the usual chimney band 9. The lower end of/the section 7 is shown provided with a resilient depending flange 7 designed to engage the flange 5 of the section 4, to maintailttlie gallery in position on the base.

In Fig.2 the burner is shown provided with the cone cap section 8, the section 7,

.and a section 44, the section 7 being posi-' tioned intermediate sections 8 and 44. In this construction, the section 7 is shown provided with a bifurcated flange portion 10, 11, to receive a flange 12 of the cone cap 8. Between said flanges 10, 11, 12 is positioned suitable insulating, or heat resisting, material indicated at 13. This material may be in the form of asbestos which is clamped between said parts, and in this figure the cone cap 1s shown fixed to the gallery. Suitable lnsulating, or heat resisting, material 13 is shown employed between the intermediate sect on 7 and the section 44. This heat res1st1ng material is shown clamped between the retaining flange 14 and anannular rib 15. In this construction the entire gallery section is removable from the base 1, the section 44 of the gallery being secured to the section 7, and provided with the retaining flange 17 to'en a e the su ortin ortion 18 of the base pp g p In Fig. 3, ,the base 1 is shown provided with an annular seat 19 on which is positloned a ring of heat resisting material 20, whlch may be of lava, magnesium or the like, said ring being provided with a recess indlcated at 21 to receive studs 22 formed on the flange 23 of the section 7 of the gallery. This ring 20 is preferably retained in position on the base 1, by the-flange 24,

although any other suitable retaining means may be employed. In this construction the cone cap 8 is removably mounted upon the section 7 as in Fig. 1. In this construction of the burner, heat from the flame will be retained in the sections 7 and 8, but restricted from traveling to the burner base 1 by the insulator 20.

In Fig. 4 the gallery is shown as having the cone cap 8 removably mounted upon the section 7, said section being shown insulated from the section 44 by a suitable non-conductor of heat indicated at 13. This nonconductor 13 may be retained between the parts 7 and 44 by the flange 14 cotiperating The outer wick tube 25 is shown provided.

with a flame protecting flange, and in Fig. 5 this flange is indicated at 27. It is proposed to mount the flange upon the,outer wick tube 25 in a suitable manner, but out of metallic contact therewith. In Fig. 5

this flange 27 is provided with a depending collar 28. metallic contact with the outer wick tube 25 by suitable heat resisting means 29 interposed between the members 25, 28. This heat resisting material 29 may be in the form of asbestos rings, which is shown between the crimped portions 30 of collar 28', and the tube retaining means 31. The upper end of the flame protecting flange may be brought into contact with the wick above the end of the outer wick tube, but out 'of contact with said tube. In this construct1on the heat is retained in the flame protecting flange, which prevents a deposit of carbon crust thereon, besides assisting in the vaporization of the oil. material 29 serves to prevent the heat from the'collar 28 being conducted down the w1ck tube 25.

In Fig. 6, the flame protecting flange 27 is shown extended across in contact with the wick 32, but out of contact with the outer wick tube 25. This embodiment of the flame protecting flange also contemplates the provision of the depending collar 28 and a collar of heatv resisting material 33, interposed between the depending collar 28 and the upper end of the outer tube 25. This heat resisting material 33 may be lava, magnesium, or any other suitable material and This collar is maintained out of- The heat resisting.

neeasve is shown provided with a retaining portion 34 at the upper end thereof, which may rest upon the upper end of ihe outer'wick tube 25. The lower end of this collar 33 may be seated upon suitable means, such as an annular retaining rib 35 on the outer wick tube 25, and if found desirable, the insulating ring 33 may be cemented to the wick tube 25 and to the depending collar 28 by a suitable heat resisting cement.

In Fig. 1, the inner wick tube 26 is shown provided with a supporting device, such as an annular rib 37 which serves as a seat for a collar or heat resisting material, indigated at 38. This material may be similar to' that shown at 33, in Figs. 6 and 7 and isinterposed between the inner wick tube 26 and the flame spreader 39, of any preferred con struction. The function of this spacing element 38 is to retain the heat within the flame spreader 39, thereby promoting combustion at a point at the upper end of the wick, and also preventing the heat, from the spreader, from being disseminated through the inner wick tube to parts where it is not desired in the burner. In Fig. 1 the spreader is shown provided with a contracted lower imperforateportion 40 and an upper perforate portion 41 to permit air from the inner wick tube to flow through the sides of the spreader to the flame. This spreader is provided also, with a conical portion 42 which may be provided with a'row of perforations to admit air from the inner wick tube to the upper part of a flame when the wick is turned to its maximum height. It is preferred to make the top plate 43 of the spreader imperforate.

While many other changes and modifications might be disclosed, not only in the gallery and base portions, but, also, in the outer wick portion and the spreader portion, the right is reserved to make such changes and alterations as will insulate a part of a burner adjacent the flame, from other parts of the burner which it is not desired to heat, as fairly fall within the scope of the appended claims, thereby maintaining the heat in those portions where they will serve to promote combustion and prevent deposit of unconsumed' matten Having thus described our invention, what We claim as new and desire tosecure by Letters Patent is:
